Pneumatic Rubber Fender Introduction
1 Outer rubber
The outer rubber layers that covers the outside of fender protects
the cord layers and the inner rubber from abrasion and other
external forces. This compound has sufficient tensile and tear
strength to withstand any weather condition and hard usage.
Standard color is black, but other colors are available on request.
2 Inner rubber
The liner of a rubber membrane seals the pressurized air inside the
fenders.
3 Synthetic tire cord layers for reinforcement
The reinforcement layers, which are made of synthetic tire cord
commonly used in tires, are arranged at ideal angles to hold the
internal pressure and to distribute the stress evenly providing
strong efficient reinforcement.
4 Beading ring
A steel ring is placed at one end (or both ends) of the fender and
holds the end of cord layers.
5 Flange
A steel flange is mounted on the fender, to which an air valve or
safety valve can be adapted.
6 Safety valve
Fenders of diameter 2500mm and larger shall be equipped with safety
valve for releasing excess internal pressure when the fenders are
over-compressed accidentally. Fender which are smaller than 2500mm
in diameter, can be equipped with a safety valve if required.
7 Metal accessories
All the relevant metal accessories of pneumatic fenders, include
shackles, towing rings, swivels, chain net, are made of stainless
steel, which are resistant for sea water corrosion.
8 Pneumatic rubber fender introduction
Inflatable rubber fender (by ball) is a marine anti-collision
product made of compressed air. Compressed air is mainly used as
the buffer medium to absorb the impact energy of the ship, making
the ship more flexible and soft when docking, so as to achieve the
effect of collision and collision avoidance. Yokohama type ball is
a kind of sheath type ball. Usually aircraft tires or engineering
tires are used to wrap the ball. Both ends are equipped with
shoulder straps, which are widely used for ship-to-ship transfer
operations and ship berthing operations. Wait. The size is: D0.5m x
L1.0m ~ D3.3m x L6.5m. Inflatable fenders (by ball) are produced in
strict accordance with ISO17357-2002 and GB/T 21482-2002
international quality standards, and their products are exported to
all over the world.
Pneumatic Rubber Fender Features
No Deterioration or Variation in Performance Yokohama Pneumatic
Rubber Fenders utilize the compressive elasticity of air, therefore
performance deterioration due to fatigue is absent.
In the case of solid rubber fenders or foam-filled fenders, based
on data were taken from comparison tests of Yokohama Fenders, there
are variations in performance. Such performance variations are
associated to changes of rubber or foam hardness occurring
as a result of cyclic compression and temperature change.
The good performance of the Yokohama Pneumatic Rubber Fenders
remains unchanged even at temperatures under -50 degrees Centigrade
(-58 degrees Fahrenheit).
Ships usually make initial contact with the dock or another ship on
STS operations at an oblique angle.
In the case of Yokohama Pneumatic Rubber Fenders, energy absorption
does not decrease at inclined compression up to 15 degrees.
